Patented July e, 1909.

Application led August 1i, 1908. `Serial No. 4128,496.

To (LIZ whom 'it may concern:

Be it known that I, Janus l. lmccs, a citizen of the United States olAAmerica, and a resident of Vl'aterloo, llzu-,lthawk county, lokwa, haveinvented certain new and useful improvements in lhnnping lfagons, oll.which the following is a. sperlieation.

My invention relates to innu'ovenients in dumping wagons, and the objectol` in v inn provenient is to providean clhcient bottonidumping wagon,and one whose reardoor is adapted for vertical displacement andadjustment when dropped, to permit it to pass without touching,- f thematerials deposited from such wagon. rlhis ohject l have accomplished bythe means which are hereinafter fully described and claimed, and whichings, in which Figure 1 is a lett-hand side elevation of in v improveddumping-wagon, showing it with its bottom-dumping' doors lowered as inoperative position to discha'uge a load. llig. 2 is e rear e evation ol'said wagon. itis'. 8 is a perspective detail ol the hand-levers andtheir rock-shafts. Fig. 4 is a detail view ol' part of theladjusting-means lor ythe rear dumping-door. i

Similar numbers re'ler to similar vparts throughout the several views.

The wagon-body l is supported on and in a l'ranie composed ol' hars 2,the latter supported on axles 49 land 53 and carrying- Wheels 42 and 40.Thel bottom ol' the box 1 consists ol' swinging-doors 1() and 1Gcoperating with an intermediate transverse ixcd )late 1.3. The forwarddoor 1G is simpl)r hinged Aat 33 direetl r to the lower llorward edgeo1' thel box 1, )ut the rear door 1() is dill'ercntly connected to therear lower edec of said box. Eyebars 9 are secured to tie rear upperedge ol' the said rear door 1l), and linlis 8 are connected between thec ves o1' said hars and the forward ends ot' cranks 3 secured, spacedapart, to `the transvol-sc rocli# The downturned left-l1and end ol' thesaid rock-shaft forms a crank whose end is pivoted to a connecting-rod'l."l1c'forwa1'd end of the rod 32 is pivoted to the lower end ol' aswing-arm 24, whose upper end is hung.,r in a bearing projectedirom theupper part 0l' the boit l. A connecting-rod 381s used to connect theswing-erin 24 and u hand-lever 34, the lower end of the latter beingpivoted at 37 te the frame 2, and said lever having a pivot'cd pawladapted to'engage the teeth of a. rack-bar 3G so as to be secured in anadjnsted'iorward or back position. ilvhen the rear door 1.0 has beenlowered l v.n1eans to be lureinal'ter described, the haunt-lever be soshifted in position'as to, by means ol' the above described .connectins, rock the shalt l'l-,vhich causes the arxns or links e to draw upsaid door`1() loclear any load whit h may have Vbeen deposited inl'rontol'it from said hex. To keep the door` 1() fron swingn ing-out ol' line,l have provided itsupper edge with a plurality e." rings LIl which passslidahly over the inclined slideshars 7, the

lower ends ol the slide-hars being secured lo' the'box 1 at itsreanlower edge., and their upper ends to a transverse liar 45 secured tothc rear lends ol the traine-hars 2.

'lhc nuineral 51 designates an adjustable. trai'isversc har having;lorifices at 'each end to receive the lilnhs oll'lbolts 5U, the lattersecured lo' said harm by nuts The loops oll said U--holts slide upontheslidehars 7, and the har 51 may be adjusted to a desired h'eig'hlalongl the hars 7 by lightening the nuts52 to secure theln togiether at4the Ine.pei"l malion. 'then thefharfrl hei-.eines a stop lor the door1U to linut thev` amount ol' its vertical' lilft.

'l`hc doors 1() and l() are lowered orclevated by means clt theharul-leve`rs 31 and 3U. Said hainl-leveasare iixcd respectiveljr to theparallel rocl-slnrl`ls 18a-nd t1T whose ends, ser Fig. 3, are niounlcdin the sides of thc traine, :nul'p'roject lhercl'roin, being turned uplo forni the eranli's 2) and 28 rcspeetivelv on each side. Said crankshave respectively eyes 2G and 27, in which are secured the forward endsol' chains 1 11 and l5 respectively, the roarclnls ol' said chainsheingsccured at 1R and at 17 respectively to the doors l0 and 1U. 'lhcnunuirals 11') and 1 1 designate brackets on the sides ol' the boxl l.lhc chain 15 on cach side is passed over an idler 21 pivoled to thebrackets aforesafrid at their point of junction, while the chain 111 oneach side is passed over idlers 2O and 12 pivotcd respectively to thebrackets 1t) and 11, this means of suspension permitting an upward draftfrom such chains upon said doors 10 and 16 without binding.

lc ower both doors at oee to dump the lentire loud, it is only necessaryto throw 1hack the lever 30, when the crank 28.011 each fsile willcontact with und force back the cranks 29 thus sluekening both of thechains 15 and 14 simultaneousl rBoth doors are raised by reversing the aove action, except that thevhandle 31 is grasped, the cranks 29 pushingforwardthe cranks 28. In ease it is desired to dump but one hall` theload, the lever 31 only is thrown back.A The load having been dumped,the forward lever 3.4 may be used to elevate the rear door 10, in orderto allow ofthe box 1 passing over the load in moving forward, withoutinterference of said rear. door with the deposited' load thereun 'keepsaidl doors tightly closed to prevent tacle, slideways, on one end tleakage, turn-buckles 54 and 55 are inserted in them as shown in Fig. 1.'The transverse partition 23 helps to so divide the load that when therear door only is opened, onl a part of the load is discharged. The rearr oor 10 when' adjusted slidably a desired height,

may bedrawn with the vehicle forward, theI lower edge of door grading toan equal height the load thereunder.

Having described -myv invention, what I claim as ne'w, and desire tosecure by Letters Patent, is:

1. In combination, a trans ortable receptacle, 'a slideway on one end tereof, said receptacle having a forwardly swinging dropdoor and arearwardly swinging' dropdoor, the latter suspended from said slidewayand adapted to slide therealong, and means for positively sliding saidrear door upward along said slideway when it is swung open.

2. In combination, a' trans )ortable receplicre'of, said receptacleIhaving a forwardly swinging dropdoor und a rearwardly swingingdrop-door, the. latter suspended on said sluleways and slidablethereover when swung open, a handlevel', a roelvsliul't, lm-vinglerank-armsflinkiing-coiineetime` bel Ween said crank-arms and saidlreni' (lropsloor, a crank-arm on said rock-shall projected therefrom atan angle to the other crank arms, and a linkingconnection between thehand-lever and said last-mentioned crank-arm.

3. In combination, a trans ortable receptacle, slideways on one endthereof, said re= ceptaclehaving a swinging .drop-door suspended fromand slidablel u ward oversaid slideways, means connecte to said dropdooradapted to move it positively upward over said slideway when swung o en,a yoke whose looped ends encircle sai slideways above and in the path ofmovement of said drop-door, and means for adjustably secur-4 ing saidyoke upon said slideways to adjustably limit the upward movement of saiddoor.

4. In combination, a transportable receptacle, swinging drop-doorstherein, two parallel rock-shafts, a hand-lever on each rockshaft, and acrank-arm on each rock-shaft, said crank-arms ada ted to become engagedand be thrown toget 1er past their dead centers when one of saidhand-levers is thrown in a certain direction, and a linking-connectionbetween each of said crank-arms and 'one or the other of saidswinging-doors respect'ively, the said doors being held closed., whensaid crank-arms are moved past thei'!` dead-centers.

5. In combination, a transportable receptacle, swinvinf' dro -doorstherein, two parallel rock-shafts, a land-lever on each rockshaft, acrank-arm on each end of each rockshaft, linking-connections het Weenthefcrank sov arms on one rock-'shaft and one of said dro l doors,linking connections, between t 1e.

crank-arms on the other rock-shaft and the other one of said drop-doors,the adjacent crank-arms on each end of said rocksliafts being adapted tobecome engaged and he thrown together past their dead-centers when oneof said hand-levers is shifted in a certain direction to elevate saiddoors toward said receptacle and hold them closed against it.
